Description

Technical Field

[0001] This utility model belongs to the technical field of dust removal devices, and more specifically, it relates to a dust removal device that can classify wood chips. Background Technology

[0002] During wood processing, a large amount of waste is generated, which needs to be cleaned up. This requires the use of dust removal devices, which are cleaning equipment that use centrifugal force to achieve gas-solid separation. The core principle is to separate dust and air through high-speed rotating airflow, thereby achieving efficient dust collection.

[0003] Based on existing technology, it has been found that existing dust collection devices typically suck in both large and small pieces of wood chips at the same time during use, making it impossible to classify the wood chips by size. Furthermore, existing dust collection devices separate dust and air through filter elements or cloth bags, but dust easily adheres to the filter elements, making them difficult to clean. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a dust removal device that can classify wood chips. This solves the problem that existing dust removal devices typically suck in large and small wood chips simultaneously into the collection device, making it impossible to classify the wood chips by size. Furthermore, existing dust removal devices separate dust and air through filter elements or cloth bags, but dust easily adheres to the filter elements, making them difficult to clean.

[0005] This utility model discloses a dust removal device for classifying wood chips, which is achieved through the following specific technical means:

[0007] The dust removal mechanism is equipped with a collection mechanism at its bottom; a filtration mechanism is installed inside the dust removal mechanism; and a cleaning mechanism is installed inside the filtration mechanism.

[0008] The dust removal mechanism includes: a main body, the bottom of which is configured as a conical structure; and an inlet is provided on the inner side of the main body.

[0010] The filtration mechanism includes a filter element, which is installed at the top of the interior of the main body.

[0011] Furthermore, a compressed air tank is provided on the top of the main body; a solenoid valve is provided on the compressed air tank of the main body.

[0012] Furthermore, the dust removal mechanism also includes a centrifugal fan;

[0013] The centrifugal fan is located on the top of the main body; the centrifugal fan has an air outlet on its side; the centrifugal fan's air intake corresponds to the top of the filter element.

[0014] Furthermore, the collecting mechanism also includes a rotating component;

[0015] The rotating component is rotatably mounted on top of screw A; the rotating component is located inside the sorting component.

[0016] Furthermore, the filtering mechanism also includes: screw B and mounting rod;

[0017] The screw B is connected to the motor inside the filter element; the mounting rod is fixedly installed at the bottom inside the filter element; there are two sets of mounting rods.

[0018] Furthermore, the cleaning mechanism includes: a moving part and a nozzle;

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. This device includes a sorting component and a rotating component. The sorting component is located at the top of the support rod, while the rotating component is located at the top of the screw A. During use, the centrifugal fan rotates, generating airflow inside the main body. This airflow is drawn into the main body through an external pipe at the inlet. The bottom of the main body is designed with a conical structure, causing the wood chips to spiral and fall inside. The spiral airflow also drives the rotating component to rotate, which in turn pushes the large wood chips falling onto the sorting component to rotate and collect them, preventing the accumulation of large amounts of wood chips. Smaller wood chips can fall through the sorting component to the bottom of the collecting component for collection, thus completing the sorting of the wood chips.

[0022] 2. This device includes a screw B and a moving part. The screw B is connected to the motor inside the filter element, while the moving part is slidably mounted on the mounting rod. During use, the compressed gas inside the compressed gas tank is discharged through a solenoid valve and connected to a nozzle through a pipe. The compressed gas is then discharged through the nozzle, and the motor inside the filter element drives the screw B to rotate, which in turn moves the moving part on the mounting rod. This allows compressed air to be sprayed at different heights above and below the filter element, thus cleaning the filter element. Attached Figure Description

[0043] In this invention, when using the device, the centrifugal fan 102 rotates, generating airflow inside the main body 101. Through an external pipe connected to the inlet of the main body 101, wood chips are drawn into the main body 101. The bottom of the main body 101 is designed with a conical structure, causing the wood chips to spiral and fall inside. The spiral airflow also drives the rotating component 205 to rotate, thus pushing and collecting large pieces of wood chips that fall onto the sorting component 203, preventing excessive accumulation. Smaller wood chips can fall through the sorting component 203 to the bottom of the collecting component 201 for collection. The wood chips are sorted in pairs. The compressed gas inside the compressed air tank is discharged through a solenoid valve and connected to the nozzle 402 through a pipe. The compressed gas is then discharged through the nozzle 402.
